[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6This utility model provides an embodiment of an air purifier that is easy to assemble and disassemble, including an outer casing 1 and a filter box 2. One end of the filter box 2 is fixedly connected to a plurality of evenly arranged fixing blocks 6. The fixing blocks 6 have positioning grooves 7 inside. The left and right sides of the inner wall of the filter box 2 are fixedly connected to sliding blocks 8. The left and right sides of the filter box 2 are both provided with slots 10. The four ends of the slots 10 are fixedly connected to first locking blocks 11. A filter screen 13 is inserted into the filter box 2. The filter screen 13 is fixedly connected to a shell 12. The upper end face of the shell 12 is fixedly connected to a connecting plate 4. The left and right sides of the connecting plate 4 are provided with through holes 17. The lower end face of the shell 12 is fixedly connected to a plurality of evenly arranged positioning blocks 14. The connecting plate 4 is connected to an insert block 15 through the through holes 17. The four ends of the insert block 15 are provided with locking grooves 16.

[0025] Please see Figures 1-5 In this embodiment, a control panel is provided on one side of the outer casing 1, a purification net 5 is fixedly connected to the upper end face of the outer casing 1, and support blocks are fixedly connected to the left and right sides of the lower end face of the outer casing 1. A vent hole 3 is opened on the front end face of the filter box 2, and an inner cavity 9 is opened inside the filter box 2. The outer shell 12 is inserted into the inner cavity 9, and the positioning block 14 is inserted into the positioning groove 7. When disassembling the filter screen 13, the insert block 15 is first pulled upward by the pulling force at one end, so that the insert block 15 is disengaged from the slot 10. At the same time, the first snap-fit ​​block 11 disengages from the snap-fit ​​groove 16 opened on the outer surface of the insert block 15. At the same time, it passes through the connecting plate 4, so that the insert block 15 is completely disengaged and fixed. Then the filter screen 13 can be taken out from the inner cavity 9. At the same time, the positioning block 14 on the lower end face of the outer shell 12 of the filter screen 13 disengages from the positioning groove 7, so the filter screen 13 can be taken out from the inside, and the disassembly is completed.

[0026] Please see Figures 3-6In this embodiment, sliding slots are provided on both the left and right sides of the outer casing 12. Two sliding blocks 8 are slidably inserted into the two sliding slots. A handle is fixedly connected to the upper end face of the connecting plate 4. Two second locking blocks 18 are fixedly connected to the four end faces inside the through hole 17. An auxiliary block is fixedly connected to the upper end face of the insertion block 15. The four second locking blocks 18 and the four first locking blocks 11 are inserted into the four locking slots 16. The insertion block 15 is inserted into the slot 10. During installation, the filter screen 13 with the outer casing 12 is inserted into the filter... The inner cavity 9 inside the box 2 allows multiple positioning blocks 14 on the lower end face of the outer shell 12 to be locked into the inner positioning groove 7 for fixation. After fixation is completed, the insert block 15 is inserted into the through hole 17 inside the connecting plate 4 and then inserted through into the slot 10 inside the filter box 2 for fixation. At the same time as insertion, the four first snap-fit ​​blocks 11 on its inner wall are snapped into the snap-fit ​​groove 16 inside the insert block 15 for fixation. This completes the disassembly and assembly of the filter screen 13, while improving its disassembly and assembly efficiency, saving time and effort.

[0027] During operation, when disassembling the filter screen 13, first pull the insert block 15 upwards at one end, causing it to disengage from the slot 10. Simultaneously, the first locking block 11 disengages from the locking groove 16 on the outer surface of the insert block 15. Since it passes through the connecting plate 4, it completely detaches and secures the insert block 15, allowing the filter screen 13 to be removed from the inner cavity 9. At the same time, the positioning block 14 on the lower end face of the outer shell 12 of the filter screen 13 disengages from the positioning groove 7, allowing the filter screen 13 to be removed from the inside, completing the disassembly. During installation... By inserting the filter screen 13 with the outer shell 12 into the inner cavity 9 of the filter box 2, the multiple positioning blocks 14 on the lower end face of the outer shell 12 are also inserted into the inner positioning groove 7 for fixation. After fixation is completed, the insert block 15 is inserted into the through hole 17 inside the connecting plate 4 and then inserted through into the slot 10 inside the filter box 2 for fixation. At the same time as insertion, the four first snap-fit ​​blocks 11 on its inner wall are snapped into the snap-fit ​​groove 16 inside the insert block 15 for fixation. This completes the disassembly and assembly of the filter screen 13, while improving its disassembly and assembly efficiency and saving time and effort.

[0028] Through the above steps, by using the pulling force to separate the insert 15 from the slot 10 during disassembly, and at the same time, pulling the filter 13 with the outer shell 12 upward, the positioning block 14 is disengaged from the positioning groove 7, thus disassembling it. This solves the problem that the existing air purifier filter 13 will accumulate dust after long-term use and needs to be disassembled and cleaned. However, the existing disassembly and assembly process is cumbersome, time-consuming, and labor-intensive.
